Where the River Flows
The Yamaska Southeast River is part of a larger network of waterways. Understanding its neighbors helps us see how water moves in this area.
- To the North: The Yamaska River is the main river that the Yamaska Southeast flows into.
- To the East: You'll find Brome Lake and the North branch of the Missisquoi River North.
- To the South: Smaller streams like Morpior stream, Pike River (Missisquoi Bay tributary), and the Sutton River are located here.
- To the West: The Écossais River and the rivière du Sud-Ouest are nearby.
River's Beginning
The Yamaska Southeast River starts from several small streams. These streams collect water from the northern side of Mont Sutton. This mountain is north of Sutton and south of Brome Lake.
The main stream that feeds the Yamaska Southeast River is called Jackson stream. It flows in from the northeast. Jackson stream also gets water from other smaller streams:
- Johnston Creek, which drains the southern part of Brome Lake.
- North Branch stream, which drains a valley to the west of "Tibbits Hill."
The Upper Part of the River
The first part of the Yamaska Southeast River is about 26.6 kilometers long. It begins where two mountain streams meet. These streams flow from the western sides of Gagnon and Écho mountains.
As it flows, the river travels:
- About 7.4 kilometers northwest through forests. It passes under the Route 215 bridge near Sutton Jonction.
- Then, it goes about 2.6 kilometers north. Here, it runs alongside a railway line and a road. This area has both farms and forests. It meets another stream coming from the southwest near the hamlet of Mansville.
- Next, it flows about 3.4 kilometers northwest through a forest. It reaches a long bay where Jackson's stream joins it from the northeast.
- It continues about 4.1 kilometers west through farmland. It passes under the Route 139 bridge in the hamlet of West Brome.
- After that, it flows about 6.6 kilometers northwest. It goes under the Route 104 bridge, which crosses a bay southeast of Davignon Lake.
- Finally, this upper section ends by crossing Davignon Lake. This lake is about 110 meters above sea level and is on the east side of Cowansville.
The Lower Part of the River
After leaving Davignon Lake, the Yamaska Southeast River continues for about 28.8 kilometers.
Here's how it flows in this section:
- It winds east for about 3.3 kilometers through Cowansville. Here, Gear Creek joins it from the southwest.
- It then flows about 4.0 kilometers northwest, winding its way to the Route 139 bridge.
- It travels about 7.2 kilometers northwest to the bridge in the village of Brigham.
- Next, it goes about 1.9 kilometers northwest to the Canadian National railway bridge.
- It makes a loop towards the north, flowing about 4.7 kilometers west. It then meets the Césaire-Mercure stream.
- Finally, it winds north for about 7.7 kilometers until it reaches its end.
The Yamaska Southeast River empties into the southern side of the Yamaska River. This meeting point is about 7.0 kilometers upstream from the Route 235 bridge in Farnham. It's also about 13.5 kilometers downstream from the highway bridge near Adamsville.
River's Name
The word "toponymy" means the study of place names. The official name "Rivière Yamaska Sud-Est" (which means Yamaska Southeast River in French) was officially recorded on December 5, 1968. This was done by the Commission de toponymie du Québec, which is like a government group that names places in Quebec.
